Latest Patents

Stuart Mac Donald's latest patents include an annuloplasty device featuring a helical anchor and methods for its use. This advanced system is designed to modify heart valve annuli, incorporating a helically anchored annuloplasty device delivered via an elongated delivery member. The device is equipped with helical anchors that rotate into the valve annulus along an anchor guide, using a driver that's movably disposed in the delivery member. Additionally, it includes a tether within the inner channel of the helical anchor and a locking device to secure the annuloplasty device after modification. This technology can be applied through traditional surgical approaches or innovative minimally invasive methods.

His second patent details a minimally invasive procedure for implanting the annuloplasty device. This method involves placing a purse string suture at a puncture site adjacent to a heart valve, inserting a delivery member, and positioning it near the valve annulus. The annuloplasty device is then deployed and implanted, allowing for reshaping of the heart valve annulus post-implantation.
